5.3.2 Other Committees Involved
Other committees are also in place to further aid in the maintenance process. The
committee names and responsibilities are listed below:
• ITS Partnership –Guide the direction and development of ITS deployment in
the Sacramento Region.
• Regional Planning Partnership – Ensure consistency of architecture with
planning objectives.
5.4 Frequency of Updates
It is important that the Sacramento Regional ITS Architecture be kept up to date in order to guide
ITS planning and deployment in the region and to keep within the intent of federal requirements.
The most effective way to ensure that a regional ITS architecture stays up to date is to establish a
regular schedule for updates. For this reason, the Sacramento Regional ITS Architecture will be
updated at regularly scheduled intervals, in coordination with the Metropolitan Transportation
Plan. The Metropolitan Transportation Plan is updated every three years. The Sacramento
Regional ITS Architecture (including the Tahoe Regional ITS Architecture) will be updated six
months in advance of the Metropolitan Transportation Plan.
It is also noted that the updates of the Sacramento Regional ITS Architecture will require
resources, whether the intention is to perform the updates in­house or contract them out. These
resources should be programmed in the overall work program. Currently, the stakeholders have
agreed that updates to the architecture will be done using an outside consultant. Cost sharing of
the updates will be established by the stakeholders prior to selecting a consultant.
5.5 What Architecture Components will be Updated?
The Sacramento Regional ITS Architecture consists of several lists and documents in various
formats, including reports, databases, and graphics. As events occur that may result in changes
to the architecture, the various components of the architecture should be updated accordingly in a
systematic fashion. A change to one of the architecture components (for example, the addition of
a project or a stakeholder) often requires other components of the architecture to be updated as
well. This is known as dependencies between architecture components.
To ensure that updates are made in all the necessary locations, Table 5.2 has been developed to
assist the architecture maintainer. This table may be consulted by the maintainer to track key
components of the Sacramento Regional ITS Architecture and to ensure that all parts of the
Sacramento Regional ITS Architecture are updated appropriately. The table describes the
different components of the Sacramento Regional ITS Architecture, their status, their location
(name of the file, document or database where the component can be found), the file format (e.g.
Word, Turbo, Visio Drawing, etc.) and their common dependencies. This will help the
maintainer organize the architecture prior to updating and make sure that all of the necessary
components are updated.
All outputs in the architecture need to be reviewed to ensure that any dependencies which are not
documented in the above table are followed through. For example, a change made to the list of
